Question
Which one of the following statements relating to multiple sclerosis (MS) is correct?Question 30Select one:a.The pathogenesis is largely due to B-cells destroying myelin sheaths surrounding neurons.b.Decreased blood brain barrier permeability may contribute to a greater incidence of MS.c.The incidence is lowest in countries far from the equator.d.MS affects females less frequently than males.e.It is a disease that affects neurons of the brain and central nervous system.
Solution
The correct statement relating to multiple sclerosis (MS) is: "It is a disease that affects neurons of the brain and central nervous system."
Multiple sclerosis is a disease of the central nervous system, which includes the brain and spinal cord. In MS, the immune system attacks the protective sheath (myelin) that covers nerve fibers and causes communication problems between your brain and the rest of your body. Eventually, the disease can cause permanent damage or deterioration of the nerves.
